passing over the evaporator fins on its way to
the vehicle interior. The refrigerant becomes a
gas again and the cycle is repeated.
Various subsidiary controls and sensors
protect the system against excessive
temperature and pressures. Additionally,
engine idle speed is increased when the
system is in use to compensate for the
additional load imposed by the compressor.
Precautions
Air conditioning refrigerant
Although the refrigerant is not itself toxic, in
the presence of a naked flame (or a lighted
cigarette) it forms a highly toxic gas. Liquid
refrigerant spilled on the skin will cause
frostbite. If refrigerant enters the eyes, rinse
them with a dilute solution of boric acid and
seek medical advice immediately.
In view of the above points, and of the need
for specialised equipment for evacuating and
recharging the system, any work which
requires the disconnection of a refrigerant line
must be left to a specialist.
Do not allow refrigerant lines to be exposed
to temperatures above 230°F (110°C) - eg
during welding or paint drying operations and
do not operate the air conditioning system if it
is known to be short of refrigerant, or further
damage may result.
Antifreeze mixture
Antifreeze mixture is poisonous. Keep it out
of reach of children and pets. Wash splashes
off skin and clothing with plenty of water.
Wash splashes off vehicle paintwork to avoid
discolouration.
Antifreeze/water mixture must be renewed
at the specified intervals to preserve its anti-
corrosive properties. In climates where
antifreeze protection is unnecessary, a
corrosion inhibitor may be used instead -
consult a Ford dealer. Never run the engine
for long periods with plain water as coolant.
Only use the specified antifreeze as inferior
brands may not contain the necessary
corrosion inhibitors, or may break down at
high temperatures. Antifreeze containing
methanol is particularly to be avoided, as the
methanol evaporates.
The specified mixture is 45 to 50%
antifreeze and 50 to 55% clean soft water (by
volume). Mix the required quantity in a clean
container.

27Correctly tension the timing belt.
28Refill the cooling system.
DOHC models
Note:Before proceeding, take note of the
following modifications: On models up to May
1990, the coolant hoses were connected to the
coolant pump housing as shown (see
illustration). On models from May 1990, the
heater hose (A) and the expansion tank hose (B)
connections were swapped over. If the hoses
are disconnected on earlier models,they should
be reconnected as on later models, ie connect
the heater hose to connection “B”, and connect
the expansion tank hose to connection “A”.
This will prevent the possibility of noises from
the heater matrix due to air in the system.
29On fuel injection models, for access to the
coolant pump, remove the air inlet hose,
plenum chamber, and air cleaner lid as an
assembly.
30Remove the coolant pump/alternator
drivebelt.

Removal
1Disconnect the battery negative lead.
2Remove the four retaining clips and
unscrew the two retaining screws, then
withdraw the upper section of the fan shroud
(see illustrations).
3The cooling fan hub nut must now be
unscrewed from the coolant pump drive
flange. A thin cranked 32.0 mm (1.25 in AF)
spanner with a jaw thickness not exceeding
5.0 mm (0.2 in) will be required (see
illustration). Alternatively, if two of the
coolant pump pulley bolts are removed, a
normal thickness spanner can be used.Note
that the fan hub nut has a left-hand thread, (ie
it is undone in a clockwise direction.) If the
pulley turns as the nut is undone, remove the
drivebelt, and clamp an old drivebelt round
the pulley to restrain it, using self-locking
pliers. Tap the spanner with a mallet if
required to remove the nut.4If required, the fan blades can be separated
from the fan hub by unscrewing the four
securing bolts.
Refitting
5Refitting is a reversal of removal, but where
applicable, take care not to overtighten the
bolts securing the fan blades to the fan hub,
as thread damage may require the whole unit
to be renewed. Where applicable, refit and

secured to the shroud in the same manner.
14Refitting is a reversal of removal, but
when fitting the fan blades, ensure that the
drive dog on the motor shaft engages with the
slot in the rear of the fan blades.
On CVH models, the cooling fan switch is
located on the right-hand side of the
thermostat housing (see illustration). On
DOHC models, the switch is located in the
end of the thermostat housing.
Removal and refitting of the switch is as
described for the temperature gauge sender.
Removal
1With the engine cold, slowly unscrew the
expansion tank cap to release any remaining
pressure from the cooling system. Remove
the cap.
2Place a suitable container beneath the

side of the heater, then detach the lower ends
of the two control cables from the heater by
removing the retaining screws (see
illustration).
6Unscrew the three securing screws, and
remove the heater control panel by sliding it
through the facia panel and withdrawing it
downwards. Disconnect the wiring from the
control panel illumination bulb.
7If necessary, the bulb can be removed with
its holder.
Refitting
8Refitting is a reversal of removal, bearing in
mind the following points.
9When reconnecting the wiring to the control
panel illumination bulb, wrap insulating tapearound the wiring loom over a length of
approximately 330.0 mm (13.0 in) starting
from the bulbholder. Route the loom, ensuring
that it is located in the two retaining clips,
bend it over and secure it to the bulbholder
with insulating tape as shown (see
illustration). This procedure will prevent the
wiring loom from chafing against the heater
control levers.
10When reconnecting the control cables to
the heater, move the control levers on the
control panel to the fully up position, then
attach the cables to the clips on the heater.
The cable ends should project from the clips
by between 0 and 4.0 mm (0 and 0.16 in). The
cables are adjusted automatically by moving
the control levers fully downwards. It is
possible that considerable resistance may
have to be overcome when moving the control
levers.
Removal
1Disconnect the battery negative lead.
2If the coolant is still hot, release the
pressure in the system by slowly unscrewing
the expansion tank cap. Place a thick rag over
the cap to prevent scalding as the pressure is
released.
3Note the location of the two heater hoseson the engine compartment bulkhead, then
disconnect and plug them (see illustration).
Alternatively, the hoses can be secured high
enough to prevent the coolant from draining.
4To prevent unnecessary spillage of coolant
when the heater unit is removed, blow into the
upper heater pipe until all the coolant has
been expelled through the lower pipe.
5Remove the two securing screws and
withdraw the heater pipe cover from the
bulkhead (see illustration). Recover the
gasket.
